Abstract: 563,484. Cycle supports. EICHNER, W. Jan. 12,1943, No. 554. [Class 136 (i)] A bicycle stand comprises a hollow body portion 10, a pedestal 12 which, when the stand is fitted to a bicycle, is movable relatively to the body portion from a free position, Fig. 3, in which it is held clear of the ground to operative position, Figs. 1 and 6, in which it projects below the lower edges of the wheels, the pedestal having a portion extending into the hollow body portion 10, securing means accessible only when the pedestal is in the free position for securing the body portion 10 to the bicycle and an automatic lock wholly enclosed within the body portion which co-operates with the portion of the pedestal inside the body portion to secure the pedestal in the operative position. As shown, the body portion 10 consists of a box-like casing carrying a cross-pin 11, on which the pedestal pivots, the casing being mounted on the fork 19, Fig. 1, of the bicycle by means of clamping plates 17, 18, one of which is riveted to the top of the casing, and a bolt 21 having a flattened end portion 24 embraced by a fork member 23 on a removable side cover 22 -to prevent the bolt being unscrewed and the stand detached. At the bottom of the side cover a flange 25 is secured to the casing by a screw 26 and when the pedestal is in the operative position, Fig. 6, a lug 27 thereon prevents the removal of the screw. The lower part of the pedestal consists of two splayed feet 13 and the upper portion is formed with a projection 14 adapted to co-operate with a nose 15 on the barrel of a lock 16 and carries a projecting pin 28 which engages a spring detent 29 to hold the pedestal in the free position. The cylindrical lock barrel 30 is disposed between the side plates 31 of a U-bracket 32 on the rear wall of the casing and is guided by a cross-bar 33 fixed to the barrel and engaging arcuate slots 34 in the plates 31. A radial slot 35 in the barrel receives the key 36, the barrel being formed with circumferential slots 38 in which engage the usual spring-loaded plates 39 to ensure that only the proper key operates the lock. In the free position, Fig. 3, of the pedestal, the key 36 cannot be withdrawn and the nose 15 on the barrel is held in the position shown by a forwardly-flexed, slotted, leaf-spring 41. When the pedestal is swung clockwise, Fig. 3, from the free to the operative position, the projection 14 presses the leaf-spring 41 back against the casing releasing the nose and allowing the spring 40 to turn the lock clockwise to a position, Fig. 6, in which the nose engages behind the projection 14 and locks the pedestal in the operative position and the key is withdrawn, the cross-bar 33 then being at the end of the arcuate slots 34. If now the key is inserted and turned to rotate the barrel anticlockwise against the spring 40, the nose 15 is displaced clear of the projection 14 and the pedestal is then swung into the free position releasing the leaf-spring. 41 which flexes forwardly to engage the nose 15. In a modification, the nose on the lock co-operates with a push-button slidable transversely in the casing, the position of the push-button determining the position of the pedestal.
